Nine photographic prints remain at large after they were stolen in a calm, daylight heist from SickKids hospital last Thursday.

Security camera footage released Tuesday by Toronto Police shows a six foot tall man, dressed all in black, strolling into the hospital with his hands in his pockets just after 6 p.m.

After piling the art onto a cart, he wheeled it outside and, according to police, may have loaded it into a four-door Mercedes. Making no attempt to conceal his identity, the thief even made sure to remove a brass plaque bearing the name of creator Darren Rigo.

“It’s kind of messed up; why would you steal from a children’s hospital?” said Mr. Rigo. “It feels like I either have an enemy or someone who really likes my work.”

The artwork had been hanging for only a month, and featured letters made from photo collages of medical instruments. Hung together, the prints spelled the nonsense word “SMROPFOAW.”
